SPECIFICATION forming part of Letters Patent No. 289,142, dated November 27, 1883.

u Applicalion filed August 24, 1883. '(No model.) l

l To all whom zit may concern:

Be it known that l, EDMUND K. Rrenrnn,

Y of swego,inthe county of Oswego,in the State of .N ew York, have invented'new and useful Improvements in Car-"Wheels, of which the following, taken in connection with. the accompanying drawings, is a full, clear, and exact description.

This invention consists ina wheel the constituent parts `of which are so constructed and combined that, while affording the maximum stability with the minimum quantity of material in the wheel, they at the same time admit of readily taking the wheel apart and of repairing or renewing any portion thereof,

all as hereinafter more fully explained, and

l vspecifically set forth in the claims.

wheel indicated.V by dotted lines.

` In the annexed drawings, Figure lis a'faoe view of my improved wheel. Fig. 2 is a face view of the tire, with the other parts of the Fig. 3 lis a transverse section on line a: ai in Fig. 1, and Fig. lisatransverse section illustrating modifieati ons in the detail construction of the wheel.

Similar letters of reference indicate corre- --sponding parts.

H denotes the hub of the wheel, provided on one end with a rigid iiange or collar, e, and on the opposite end with a removable collar,

l 3o f, tted to the periphery of the hub and heldthereon b bolts c c. assin@ transverselv Y P s `through the two collars.

S S represent the spokes, the inner ends ofwhich rest on the hub and are mitered or fitted closely side to side, and secured in position by the bolts c clamping them between the two collars e f. Theouter ends of the spokes terminate in segments C, which are also each mitered or fitted to abut against the ends of the adjacent segments. The outer peripheral face of said segments is provided with one or'morelongitudinal grooves, c, into which rit a corresponding number of ribs, b, on the inner periphery of a tire or peripheral ring, B. The described constituent parts of the wheel are thus securely locked together. In

order to admit of readily uniting them and as readily separating them when required for repairs or renewal, the rib Z is terminated with'a blank space, d, of sufficient length to receive one of the segments C'. Before applying the collar f to the hub H, the several segments are successively introduced in the space cl, and then shifted around the tire B, with the rib b of the latter engaging the groove a ofthe segments. After all the segments are thusintroduced they are arranged to bring the joints of two of the segments into the center of the length ofthe space d, and thus maintain all l the segments in engagement with the rib Z) of 6o* the tire. By means ofthe bolts o c drawing the collar f against the inner ends of the spokes, and bolts c c passing through the segments at the joints thereof and through' the rib b, the segment-s are securely locked in their position. i

If desired, the spokes S, with their segments C, may be divided parallel to the plane of the I wheel, as illustrated in Fig. el of the drawings, in which case the bolts c c will necessarily have to be larger in order to hold the said parts united and resist the lateral strain exerted on said parts by the rib b in the groove a. y Such construction, however, will dispense v with the blank space d in the rib b, inasmuch as the sections can be applied from opposite sides of the wheel 'and then secured by the bolts c and c.

Having described my invention,what Iclaim as new, and desire to secure byLetters Patent, isy l. In combination with the spokes termia nating in segments G, provided with the groove c, the tire B, having the rib b, and the blank space cl, adapted to receive one oi' the segments, and the bolts c e, passing through the segments and through the rib b, substan-v vtially'as specified and shown.

2. The combination ofthe hub H, provided with the collar e, the removable collar f, the spolges S, clamped between said collars and having their outer ends terminating with segments C, provided with the groove c, the tire B, provided with the rib b and blank-space d, bolts cf, for fastening the collar f, and bolts c, passing through the'segments and through the rib b, all constructed and combined substantially' in the manner described and shown.

In testimony whereof 'I have hereunto signed my nume stud afixed my seul, inthe presence 1o of two attesting Witnesses, at Oswego city, in the county of Oswego, in the State of New York, this 21std2ty of August, 1883.
